No full textTürkiye, iş kazaları özellikle maden kazaları konusunda dünyada üst sıralarda yer almaktadır. Maden sektöründe meydana gelen kazaların en temel sebepleri arasında, hiç şüphesiz çalışanların iş güvenliği ve sağlığı hususunda arzu edilen düzeyde bilgi ve donanıma sahip olmaması, kaza riskini asgariye indirecek ya da ortadan kaldıracak yeterli birikime sahip olmamaları bulunmaktadır. Maden sektöründe iş görenlerin iş sağlığı ve güvenliği farkındalıklarının yeterince gelişmemesinden kaynaklı meydana gelen kazaların çoğunlukta olması, bu sektördeki uygulamaların incelenmesini önemli kılmaktadır. Bu bağlamda bu çalışma perlit maden işletmelerinde iş görenlerin iş sağlığı ve güvenliği algı düzeylerini tespit etmek amacıyla yapılmıştır. Bu maksatla, Türkiye geneli Perlit Maden işletmeleri çalışanlarının iş sağlığı ve güvenliğine yönelik bilgi düzeyleri belirlenmeye çalışılmıştır. Tarama modelinde tasarlanan bu araştırmanın evrenini, Perlit maden işletmelerinde çalışanlar oluşturmaktadır. Araştırmanın örneklemi ise basit tesadüfi yöntemle seçilen, 200 gönüllü katılımcıdan oluşmaktadır. Araştırmada, katılımcıların iş sağlığı ve güvenliğine yönelik algı düzeylerini tespit etmek amacıyla "İş Sağlığı ve Güvenliği Uygulamaları Performans Değerlendirme Ölçeği" kullanılarak 200 gönüllü katılımcıdan veri toplanmıştır. 200 gönüllü katılımcıdan elde edilen bu veriler SPSS programıyla analize tabi tutulmuştur. Yapılan analizler sonucunda, Perlit maden işletmelerinde çalışan işçilerin iş sağlığı ve iş güvenliğine yönelik algılarının yüksek düzeyde olduğu tespit edilmiştir. Ayrıca, demografik özelliklere göre perlit maden işletmelerindeki çalışanların iş sağlığı ve iş güvenliğine yönelik algı düzeylerinin farklılık gösterdiği tespit edilmiştir. Araştırma sonucunda elde edilen bu bulgular ışığında, çalışanlara iş sağlığı ve güvenliği eğitimlerinin uygulamalı olarak eksiksiz bir şekilde verilmesi ve iş görenlerin iş sağlığı ve güvenliğine dair farkındalıkları hizmet içi eğitimlerle arttırılması önerilmektedir.Turkey is located in the upper row in the world for mining work accidents. One of the main reasons for accidents in the mining sector is undoubtedly that the employees do not have the desired level of knowledge and equipment on occupational safety and health, and that they do not have sufficient accumulation to minimize or eliminate the risk of accidents. The fact that the accidents occurring due to insufficient development of occupational health and safety awareness of the employees in the mining sector makes it important to examine the practices in this sector. In this context, this study was carried out in order to determine occupational health and safety perception levels of perlite mining enterprises. To this end, knowledge of occupational health and safety for the general Perlite Mine employees have been determined. The universe of this study, which was designed in the survey model, consists of the workers in Perlite mining enterprises. The sample of the study consisted of 200 volunteer participants selected by simple random method. In this research, data were collected from 200 volunteer participants by using Occupational Health and Safety Practices Assessment Scale "in order to determine the perception levels of the participants regarding occupational health and safety. The data obtained from 200 volunteer participants were analyzed with SPSS program. As a result of the analyzes, it was found that the perceptions of workers working in Perlite mining enterprises in terms of workers' health and safety were high. In addition, according to demographic characteristics, it was found that perlite mining enterprises employees' perception of worker health and safety differed. In the light of these findings, it is recommended that occupational health and safety trainings are given in a practical manner and that the awareness of employees on occupational health and safety is increased with in-service trainings

Production and biological properties of nano porous glass microparticles for anticancer drug carrier
No full textNanoporous glass (NPG) microparticles were produced by conventional melt-quenching followed by acid-alkali leaching to get material for anticancer drug carriers. NPG exhibited a positive zeta potential of 34 mV after [3-(2-aminoethylamino) propyl] trimethoxysilane treatment. The specific surface area and the total pore volume of NPG were 47.3 m2/g and 0.692 cm3/g, respectively. The 5-Fluorouracil (5FU) loading capacity of NPG was measured as 18.2 ± 0.2 mg5FU/gNPG. The drug release rate was monitored for 120 hours. To evaluate the cytotoxic effects of NPG on both MCF-7 breast cancer cells and MCF-12A, an immortalized cell line, the study employed the 2, 3-bis [2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium5-carboxanilide inner salt (XTT) assay. The XTT results revealed that NPG showed a time and concentration-dependent cytotoxic effect. It is anticipated that NPG is a safe and effective material for drug delivery systems for in vitro and a promising alternative material for in vivo applications
Energetska varnost v času krize: študiji primera Bolgarije in Srbije
No full textThis thesis aims to assess the EU’s external energy policy and to what degree it has been embraced by small states during the energy crisis by posing the question, “How does European Union membership influence the external energy policy decisions of small states within the foreign policy dimension during energy security crises?”. To answer this, the research is taking Bulgaria and Serbia as case studies due to their similar population sizes, GDP, and energy consumptions. This research conceptualizes energy security and energy diplomacy to understand how diplomacy and energy dependencies are interrelated and how this relationship can be utilised as a tool in international relations. Through supporting the qualitative work on foreign policy analysis with the quantitative analysis of the energy industry structures and energy dependencies of Serbia and Bulgaria in a comparative manner, this research is conducting mixed research on the issue. The comparison of Bulgaria and Serbia enables the author to analyse and understand the role of EU membership
How Should Professional Psychiatric Associations Respond To a Large-Scale Disaster
No full textEsen, Emre Cem/0000-0003-4535-389X; Mutlu, Emre/0000-0001-6604-2105Disasters pose unique challenges, triggering significant psychological and social crises with both short- and long-term impacts. In this article, we address the critical role of professional psychiatric associations (PPAs) in responding to large-scale disasters, emphasizing the operational model connected with the Psychiatric Association of T ; uuml;rkiye's (PAT) response to the 2023 earthquakes in T ; uuml;rkiye and Northern Syria. We propose the SOLIDARITE model, a structured response framework, which incorporates sustained preparedness, organized networks, resource libraries, on-site and remote interventions, and comprehensive disaster planning across early, middle, and long-term phases. The model emphasizes a multidimensional approach integrating pre-disaster preparedness through training, various psychosocial support options, the establishment of networks, and the formulation of a master disaster response plan. The implementation of this model by PAT during the 2023 earthquakes facilitated an effective and prompt response, underlining the importance of PPAs' role in disaster preparedness and action. The SOLIDARITE model supports the need for deeper integration of disaster psychiatry into psychiatric training and calls for national and international collaboration to enhance the preparedness and response capacity of PPAs.The authors present their sincere gratitude to Disaster Preparedness and Intervention Unit, PAT Committees and Sections, and all members who made outstanding efforts through volunteer activities for the February 6, 2023, Earthquakes.PAT Committees and Section

NT-proBNP levels and mortality in a genera population-based cohort from Turkey: a long-term follow-up study
No full textAim: We investigated the relationship between NT-ProBNP and mortality in a general population-based cohort. Methods & Results: A total of 2021 out of 4650 participants from previously published HAPPY study were included. Mean follow-up was 84.5 +/- 10.4 months. After adjusting for risk factors, high levels of LogNT-proBNP predicted all-cause death (HR: 3.23; 95% CI: 2.20-4.75; p < 0.001) and cardiovascular death (HR: 3.85; 95% CI: 2.37-6.26; p < 0.001). Regression analysis revealed that LogNT-proBNP was an independent predictor of all-cause death (HR: 2.85; 95% CI: 1.91-4.24; p < 0.001) and cardiovascular death (HR: 3.02; 95% CI: 1.84-4.95; p < 0.001). Conclusion: Our study showed that in long term follow-up, NT-proBNP is associated with increased all-cause and cardiovascular mortalit
Obstrüktif Uyku Apnesi Olan Hastalarda Koblatörle Dil Kökü Rezeksiyonu Cerrahisi Sonuçlarının Polisomnografi ve Manyetik Rezonans Görüntüleme İle Değerlendirilmesi
No full textMutlu, H. Evaluation of coblator assisted tongue base resection surgery results with polysomnography and magnetic resonance imaging in patients with obstructive sleep apnea. Hacettepe University School of Medicine, Department of Otolaryngology, Thesis, Ankara, 2019. Due to the low cost, low complication and morbidity, tongue base resection with coblator has been used frequently in the treatment of OSA in recent years. The aim of our study is investigate the relation of polysomnography (PSG) parameters with volumetric changes which is obtained by surgery. In our study, 24 patients in 18-65 age range are included. Patients which are diagnosed as moderate or severe OSA and tongue base grade 2-3-4 according to Cormack-Lehane classification and more than %50 obstruction in the tongue base with Müller maneuver are included. Magnetic resonance imaging (MRI) has done in all patients, in preoperative and postoperative 3-6.month period. Preoperative and postoperative tongue base and retroglossal airway volumes were measured using three-dimensional applications program on GE PACS study station. Preoperative mean apnea-hypopnea index (AHI) is 42.2±22.5, postoperative mean AHI is 29.9±17.7 and statistical significance is found between this values (p<0.001). We measured the preoperative mean tongue base volume 49.2±7.4 cm3, postoperative 37.5±8.3 cm3 (p<0.001); also we found mean retroglossal airway volume preoperative 11±3.3 cm3, postoperative 16.7±4.8 cm3 (p<0.001). No statistically significant correlation is detected between tongue base and retroglossal airway volumetric changes and evaluated PSG parameters as AHI, supine AHI, nonsupine AHI and oxygen desaturation index (ODI). Retroglossal airway volume has increased %96.5±97.9 in surgically successful group and %46.9±30.8 in unsuccessful group. Tongue base volume has decreased %33±11.2 in surgically successful group and %20.2±13.9 in unsuccessful group. Nevertheless statistically significant difference couldn’t found between successful and unsuccessful patient groups. As a result coblator asisted tongue base surgery achieve an objective decrease in tongue base and also objective increase in retroglossal airway volume. However the findings show that, there is no statistically significant relationship between alterations in AHI and tongue base and retroglossal airway volume changes. This result is attributed to multifactorial pathophysiology of OSA.Mutlu, H. Obstrüktif uyku apnesi olan hastalarda koblatörle dil kökü rezeksiyonu cerrahisi sonuçlarının polisomnografi ve manyetik rezonans görüntüleme ile değerlendirilmesi. Hacettepe Üniversitesi Tıp Fakültesi KBB Anabilim Dalı, Uzmanlık Tezi, Ankara 2019. Koblatörle dil kökü rezeksiyonu, düşük maliyet, düşük komplikasyon ve morbidite sebebiyle, OUA tedavisinde son yıllarda oldukça sık uygulanmaktadır. Çalışmamızda cerrahi sonrasında elde edilen hacimsel değişiklikler ile polisomnografi (PSG) parametreleri arasındaki ilişkinin incelenmesi amaçlanmıştır. Çalışmamıza orta ve şiddetli OUA tanısı alan, Cormack-Lehane sınıflamasına göre dil kökü evre 2-3-4 olan; Müller manevrası ile %50’den fazla obstrüksiyon tespit edilen, 18-65 yaş aralığında 24 hasta dahil edilmiştir. Hastalara preoperatif dönemde ve postoperatif 3-6. aylar arasında MRG yapılmıştır. Preoperatif ve postoperatif dil kökü ve retroglossal havayolu hacimleri GE PACS iş istasyonu üzerindeki üç boyutlu uygulamalar programı ile ölçülmüştür. Preoperatif apne-hipopne indeksi (AHİ) ortalaması 42.2±22.5, postoperatif AHİ ortalaması 29.9±17.7 olarak bulunmuş ve istatistiksel olarak anlamlı fark saptanmıştır (p<0.001). Dil kökü hacmi ortalaması preoperatif 49.2±7.4 cm3, postoperatif 37.5±8.3 cm3 ölçülürken (p<0.001); retroglossal havayolu hacmi ortalaması preoperatif 11±3.3 cm3, postoperatif 16.7±4.8 cm3 olarak tespit edilmiştir (p<0.001). Dil kökü ve retroglossal havayolu hacmindeki değişikliklerin, AHİ, supin AHİ, nonsupin AHİ ve oksijen desaturasyon indeksi(ODİ) başta olmak üzere değerlendirilen PSG parametreleri ile istatistiksel olarak anlamlı korelasyon göstermediği saptanmıştır. Retroglossal havayolu hacmi, cerrahi olarak başarılı grupta %96.5±97.9; başarısız grupta %46.9±30.8 artmıştır. Dil kökü hacmi, cerrahi olarak başarılı grupta %33±11.2, başarısız grupta %20.2±13.9 azalmıştır. Ancak başarılı ve başarısız hasta grupları arasında istatistiksel olarak anlamlı fark bulunmamıştır. Sonuç olarak koblatörle dil kökü rezeksiyonu, dil kökünde objektif küçülme, retroglossal havayolu hacminde de artış sağlamaktadır. Ancak ortaya konulan bulgular, dil kökü ve retroglossal havayolu hacim değişikliklerinin AHİ’deki değişim ile istatistiksel olarak anlamlı bir ilişkilide olmadığını göstermektedir. Bu sonuç OUA patofizyolojisinin multifaktöriyel oluşuna bağlanmıştır
The Predictive Value of Flow-Mediated Dilation and Carotid Artery Intima-Media Thickness for Occult Coronary Artery Disease
No full textBackground: Multidetector row computed tomography (MDCT) is an attractive noninvasive alternative to assess overall coronary artery disease (CAD) burden and may reveal coronary plaques, which may be underestimated by conventional coronary angiography. The aim of this study was to determine whether brachial artery flow-mediated dilation (FMD) and carotid artery intima-media thickness (CIMT) might accurately predict patients with occult coronary plaques whose conventional coronary angiographies revealed normal coronary arteries (NCA). Methods: Thirty-five patients with angiographically NCA were consecutively recruited into the study. They underwent MDCT and were divided into NCA group (18 patients; 8 male; 47 +/- 9 years) and occult CAD group (17 patients; 11 male; 50 +/- 10 years) according to presence of coronary plaque. Nineteen consecutive patients with evident CAD (16 male; 54 +/- 7 years) and 19 healthy subjects (10 male; 50 +/- 6 years) were included as control groups. FMD and CIMT were measured by brachial and carotid artery ultrasonography. Results: Occult CAD group had significantly lower FMD and insignificantly higher CIMT than NCA group whereas they had significantly higher FMD and insignificantly lower CIMT than evident CAD group. NCA group had significantly lower CIMT than evident CAD group. Receiver operating characteristic curve analysis demonstrated FMD < 8% (sensitivity: 94.4%; specificity: 73.0%; PPV: 77.3%; NPV: 93.1%) and CIMT = 0.65 cm (sensitivity: 72.2%; specificity: 62.2%; PPV: 65.0%; NPV: 69.7%) could predict patients with CAD. FMD and CIMT were independent predictors of CAD (P < 0.001; OR: 45.630; 95%CI: 5.38386.983 and P = 0.015; OR: 14.226; 95%CI: 1.666121.467, respectively). Conclusion: FMD and CIMT might predict patients with occult CAD and be helpful in selecting patients for MDCT. (Echocardiography 2011;28:1141-1147
Investigation of Factors That May Affect the Commitment of Healthcare Professionals to Their Works During the COVID-19 Pandemic Period
No full textThe environment of uncertainty created by the COVID-19 pandemic period has caused difficulties especially for healthcare professionals in their work activities. The purpose of this research is to find out which variables might affect the commitment of healthcare professionals to their works during this COVID-19 period. Based on the data announced by the Ministry of Health during the pandemic in the first quarter of 2021, it was decided to conduct a research on doctors, nurses, caregivers, and medical secretaries working in hospitals in the cities of the Eastern Black Sea Region of Turkey which generally show high risk. In the developed research model, satisfactory conditions (SC), emotional commitment to change (ECC), and psychological ownership (PO) as variables that may directly or indirectly affect the commitment of healthcare professionals to their works (CW) were used. The Smart PLS program was used in the analysis of the research model and hypothesis. It was seen that the ECC of healthcare professionals has a positive and significant (.694; p .086). Looking at the indirect (intermediary) effects obtained as a result of the research, it was seen that all of the hypotheses consist of positive coefficients. This situation reveals that the mediating variables have complementary effects on the obtained results. © The Author(s) 2022.WOS:00078698580000
